Here is a circuit that will output a PWM wave good for varying the speed of a DC motor. Why is this not going to work? How would you fix it? The 555 timer can’t handle that type of load, and it is not ...

Counter/timer hardware is a crucial component of most embedded systems. In some cases a timer is needed to measure elapsed time; in others we want to count or time some external events. Here's a ...

Raspberry Pi enthusiasts looking for inspiration for projects to use the new Raspberry Pi Pico microcontroller, which is now available to purchase priced at just $4, may be interested in a new Pico ...

The project aims to create a PWM controller that contains a frequency range from about 170 to 200Hz to achieve a pulse width regulation featuring almost 0-100% with a relatively stable oscillator ...
